A car covers first half of the distance in the following manner :
(i) 1/4th of the distance is covered at a speed v1 and next 1/4th of the distance is covered with a speed of v2.
(ii) First half of the time, for half of the journey it moves at a speed v1, and for the next half of the time it moves at a speed v2. Then, the next half is covered with a speed v3. Find the average speed.
Please explain with proper diagram.

Answer:
Explanation:
WE KNOW,
THAT IF DISTANCE IS EQUAL
WE CAN USE FORMULA OF AVERAGE SPEED AS
2V1*V2/V1+V2
SO BRO YOU CAN CALCULATE THE AVERAGE SPEED BY USING THIS FORMULA
IN 1ST PART
YOU CAN DO AS
2V1*V2/V1+V2
AND IN 2ND PART YOU CAN DO AS
3V1*V2*V3/V1+V2+V3
BY CALCULATING THESE YOU CAN APPLY THIS FORMULA ONES AGAIN BY THE VALUE COMES AFTER CALCULATING.
I AM ALSO GIVING YOU 2 FORMULA FOR AVERAGE SPEED
IF TIME INTERVAL IS EQUAL THEN FORMULA=V1+V2/2
BUT IF DISTANCE IS EQUAL=2V1*V2/V1+V2
SO BY USING THESE FORMULAS YOU CAN EASILY SOLVE QUESTION RELATED TO AVERAGE SPEED...........
HOPING ITS HELFUL!!!!!
